Broader Industry Critiques Relevant to Primetals

The industry, in which Primetals Technologies operates as a provider of production technologies, faces substantial criticism for its environmental footprint, accounting for approximately 7-9% of global annually, primarily from energy-intensive processes like blast furnace-basic oxygen furnace (BF-BOF) routes that rely on coal-derived . This contribution exceeds the emissions of entire nations like and persists despite incremental efficiency gains, as the sector's expansion in high-emission regions outpaces reductions elsewhere. Critics argue that conventional technologies supplied by firms like Primetals enable continued reliance on fossil fuel-based reduction, exacerbating and health risks, with coal-based steel plants in the U.S. alone emitting toxic pollutants linked to respiratory diseases and premature mortality. Decarbonization efforts highlight further industry-wide challenges relevant to providers, including the technical and economic hurdles of transitioning from BF-BOF (which dominates 70% of global production) to alternatives like furnaces (EAF) or (H2-DRI), which require massive infrastructure overhauls, renewable energy scalability, and investments spanning 10-15 years with multibillion-dollar costs. While providers offer hybrid solutions, skeptics point to slow adoption—global low-carbon steel share remains below 30%—attributing delays to profit margins squeezed by high upfront costs and inconsistent policy support, rather than insurmountable barriers, potentially locking in emissions for decades. Market distortions from global overcapacity, particularly China's production of over half the world's steel, amplify critiques by flooding markets with subsidized exports—reaching 118 million tonnes in 2024—undermining competitiveness for technology-dependent producers in Europe and North America, where Primetals' clients operate under stricter environmental regulations. This overcapacity, projected to hit 721 million tonnes by 2027, is seen as state-driven rather than demand-led, distorting prices and incentivizing retention of outdated, high-emission tech over innovative upgrades, thus hindering the industry's shift to sustainable models. Such dynamics raise questions about the efficacy of Western tech providers' green innovations in a landscape where cheaper, less-regulated alternatives prevail.
